Specification of Letters Patent.

Patented Nov. 12, 1918.

Continuation in part of application Serial No. 73,468, led January 21,1916. This application filed August 21, 1916. Serial No. 116,047.

To all whom t may concern.'

Be it known that I, MATHiAs R. KoNDoLF, a citizen of the United States,residing at Rochester, in the county of Monroe and State of New York,have invented certain new and useful Improvements in Boxes, of which thefollowing is a specification.

The object of this invention is to provide a box made up of two or moreconsecutive sections placed one within the other.

Another object of the invention is to provide a process by which saidbox may be made.

These and other objects of the invention will be fully illustrated inthe drawings, described in the specification and pointed out in theclaims at the end thereof.

In the drawings,

Figure 1 illustrates one of the blanks used for the making of a sectionof my improved box.

Fig. 2 illustrates another one of the blanks used for the making ofanother section of my improved box.

Fig. 3 is a perspective view showing the blank of Fig. 2 partly folded.

Fig. 4 is a perspective view showing the blank of Fig. 1 partly folded.

Fig. 5 is a perspective view showing the blank of Fig. 3 completelyfolded into a box section and partly inserted in the section formed bythe folded blank shown in Fig. 4.

Fig. 6 is a perspective view of the completed box.

Fig. 7 is a plan view of the reinforcing blank.

Fig. 8 is a perspective view of the reinforcing blank partly folded.

Fig. 9 is a perspective view of the finished box partly broken awayshowing the inner and outer sections and the section formed from thereinforcing blank between them.

Figs. i0, ii, 12, 13, 14. and show different forms of blanks by whichsections for boxes of this same type may be made.

Figs. 16, 17, 18 and 19 show diiferent forms of blanks from which thelocking strips are omitted, other forms of locking devices being usedinstead.

Figs. 20 and 21 show the blanksof Figs. 18 and 19 folded up intosections.

In the drawings like reference numerals indicate like parts.

In the drawings reference numeral 1 indicates the blank shown in Fig. 1and reference numeral 2 indicates the blank shown in Fig. 2. The blankshown in Fig. 1 is cut on the full 'lines 3, 4, 5 and 6 and is bent orfolded on the dotted lines, on which lines it may or may not be scored.The part indicated by reference numeral 7 will form the bottom of thebox. Reference numerals 8 and 9 indicate the sides of the box and 10land 1l indicate the ends of the box. The sides and ends will first bebent up so as to stand at right angles to the bottom 7 after which thecorner pieces 12, 13, 14 and 15 will be bent at right angles to the endsso as to lie parallel to each other and be embraced within the sideswhich would necessitate bending up the sides of the box last, afterwhich the top edges or locking strips 16 and 17 of the sides 8 and 9 maybe folded down over the corner pieces locking all the parts together.This will form the outer section of the box.

The blank 2, shown in Fig. 2, will be cut on the full lines 20, 21, 22and 23 and will be folded on the dotted lines. In this blank, 24 willform the bottom of the box. 25 and 26 will form the sides of the box and27 and 28 will form the ends of the box.

The sides and 26 will `first be bent up at right angles to the bottom 24after which the ends 27 and 28 will also be bent up at right angles tothe bottom of the box. The corner pieces 29, 30, 31 and 32, which areattached tothe ends of the sides 25 and 26, will then be bent over theends of the box, in which case the outer portions of the corner pieces33, 34, 35 and 36, marked with dotted lines, will project beyondthe endsand will be folded parallel to the side opposite to the one to whichthey are attached 0r if the box is of such a width they will merely foldagainst the ends. The upper margins -or locking strips 37 and 38 of the`ends 27 and 28 will be folded down over the overlapping corner pieces,thus locking all the parts of the section together.

In the section of the box formed from the blank in Fig. 1, the lockingstrips 16 and 17 will project on the inside of the section and in thesection of the box formed from the blank shown in Fig. 2, the lockingstrips 37 and 38 will project on the outside of the section. As thesection formed from the blankM in Fig. 2 will ordinarily be put insideof the section formed from the blank shown in Fig. 1,both Xsetsoflocking strips will bc `confined between'th'e two sectionsby 'whichtheyV will be heldsecurelyin place. if the positiony of the sections isreversed, the locking stripsineach case will be bent in the oppositedirection and the other partsof fthe 'section wil-l be folded tocorrespondso that :in the finished box-the The' box is finished 'byinserting 'the inner section Iof the box' in the outer Isection yandpushing it down "therein, until the bottoms come together, Fig. '5showing th'e'ltwo sections partly `joined land Fig. 6 showing the twosections 'fully joined. l Other methods of'a'ssemblingthe sections willbedescribed hereinafter;

lThe blanks -ffrom which the sections are formed will preferably 'becoated on one side with an adhesive coating'so 4that the coating willbeon the members 'that are adjacent when 'the sections are folded andbrought together;`

'I have described-two sections joined together making a complete box,although it is obvious that any greater number of sections might in likemanner be made vand joined together in a single box.

If it is desired to give the box a turned edge, the locking strips,instead of being folded sofas to be held between the two boxes, will berleft in such position that after the sections vare brought'together thelocking strips on 'the inner section can be folded over' and'leftprojecting outside of the ou'ter section and' the lockingstrip's on theouter section can be folded over and left projecting inside of the innersection. To dothis the sections must be inserted in such a manner sothatone set of locking strips are intermediate the other-set in the finishedbox. 'In this lstyle box the locking -strips shouldbeffastened byyadhesive or otherwise, andadditional lockingr hooks on the cornerpieces, as shown in Fig. 16, should 'preferably-be used.

As shown in Fig. 6 the locking strips are turned as shown at 40 and .4land left exposed to form a turned edge and conceal the layers of thesections, while at 42 and 43 the locking strips are folded and concealedbetween the sections so as to leave the edges or layers of the sectionsexposed.

After the box has been assembled, as above described the sides areforced together by hand or a male and female die or by air pressure,using the apparatus and the proeess described in my application No.67.890,

'sled December 20, i915 and 77,265 "filedy lFebruary 9, 1916, both 4vofwhich lare copending, in which case the dies 'would be formed tocorrespond with the box and the air pressure could be applied either tothe outside or the inside of the box.

It will also be understood that a box made in accordance with the vabovecan `be readily reinforced and in Fig. 7 I have shown av -blank .45which may be used for the purpose of reinforcing the box The blank shownis provided with a bottom member-and 'side and vend members integraltherewith. 'The side and end -members'will be' bent up asisillustratedinFig. '.8 and the reinforcing section will bev inserted' inthe outer section before the inner sectionfis inserted therein yor maybeplaced 'over'lthe inner section and inserted' Ywith it' in the outersection. If desired lthe reinforcing may be limited merely vto-'thesides vor lends or bottom in which case 'the reinforcing blanks would be-cu'tto correspond vand inserted as abover` described.

Boxes made in sections and then putftogether as described herein areparticularly adapted 'to lhave heavy and bulky reinforcements placedbetween the sections, andit'is entirely feasible and ypracticable'tousesuch material as rotary-'cut veneer wood-in its usual warped Yandcurled condition for this purpose without adecting the shape -of thebox.

In :this manner extra bottom, side and end members as well as 'metalstraps or devices used to fasten the box covers can'be includedlgetween'the layers and become a part of the IIn describing Figs. 10,`12 and 14"like parts have been indicated by the same 'referencecharacters that have been used in describing the corresponding 4parts inFig. 1 the reference character a beingia'dded to the characters in Fig.10 -referencelcharacterfb to theicharacters in Fig. 12an'd referencecharacter c tothe characters vin Fig. '14.

In describingFigs. 11, 13and`15'like parts have beenindicate'd by thesame refy erence 'f characters ith-at have been used in describing lthecorrespondingparts in Fig. 2 the reference character a being added tocharacters in Fig. 11 reference character b nasaeoe l to the characterin Fig. 13 and reference character c to the characters in Fig. 15.

In Figs. 10 and 11 I have illustrated blanks for a similar outer andinner section, the blanks being cut along the solid lines and'foldedalong the dotted lines.

It will be understood that the box folded from the blanks shown in Figs.1 and 2 will be rectangular with all corners square, while the boxformed from the blanks shown in Figs. 10 and 11 will have the ends andsides tapered or out of :parallel with each other and connected byangular corners with the bottom of the box-and the opening at the top ofthe box rectangular in outline. i

The blanks, shown in Figs. 12 and 13 will form abox in which the endsand sides are tapered and are vconnected by round corners. The boxformed from the blanks, shown in Figs. 14 and 15 will have parallelsides and ends connected by round corners and in this box the opening atthe top of the box will be of substantially the same dimensions as thebottom of the box. In these boxes, the locking strips are disposed onthe blanks with the two sections so that they will come in the one blankat the ends of the box and inthe other blank at the sides of the box andthe locking strips can be turned into the space between the sections orcan be turned over the edges of the box to form a turned edge. i y

In cases where blanks similar to any one of the blanks shown in Figs. 1to 15 are used, the locking strips of both sections may be folded to lieinv the space between the two sections or one set of them may be' foldedt so as to lie between the sections and the other locking strips may befolded over the other section to make a turned edge.

In the box formed from the blanks shown in Figs. 12, 13, 14 and 15, thebottom members will be cut with square corners, which square corners 90,91, 92 and 93 can be turned up and held between the sections to eal andstrengthen the lower corners of the It will be noted that in each blankshown in Figs. 1 to 15 the end and the side members are arranged inpairs and are formed integral with the bottom and that members of onepair will always be wider than the members of the other pair, the excessof lstock being used to form the locking strips and that in each box thelocking strips will be on 'the sides in the one section and on the endsin the other section. It will also be noted that these locking stripswill be integral with one pair of members and lapping or corner pieceswill be integral with the other pair of members which lapping pieceswill connect the adjacent sides and ends and will in turn be held inplace by the locking strips.

It will be understood that the 'locking strips or pieces may be of anywidth and may be folded to form pockets around the top of the box toreceive the flanges of the cover' or to reinforce the box as is moreparticularly described in my co-pending application Serial No. 80,876,filed February 28, 1916. rIhe corner pieces may be lengthened to matchthe Width of the side and end members in each blank and the extra stockmay be use-d to reinforce the box.

In Figs. 16, 17, 18 and 19 I have shown blanks with other forms oflockingdevices.

In Figs. 16 and 17, 50 indicates the bottom members to which areattached the side members 51 and 52 and the end members 53 and 511. InFig. 16 are provided the corner pieces 55 and 56 which are carried onthe side member 51 and the corner pieces 57 and 58 which are carried onthe side member 52. The corner pieces 55 and 58 have hooked shaped ends59 and 60. The hooked end 59 is intended to engage with the slot 61 andthe hooked end 60 is intended toengage with the slot 62 when the blankis folded into the section.

In Fig. 17 the corner pieces 63 and 64 are attached to the end member 53and the corner pieces 65 and 66 are attached to the end member 541. The.corner piece 61- is slotted to form a tongue 67 that engages with theslot 68 when the blank is folded into sections and the corner pieces 63and 65 are slit at 69 and 70 so as to engage and interlock with each`other when the blank is formed into the section.

It will alsobe understood that any one of the typos oit locking devicesshown in any of the gures may be used in any of Jthe sections oranycombination of these locking devices may be used in the varioussections.

In Figs. 18 and 19 I have shown another form of blank of which twoblanks may be cutfrom a single rectangular sheet with practically nowaste of stock, although it maybe desirable to form blanks of this sortof such dimensions as to make it impractical to cut both of them from asingle rectangular sheet without waste. In these` figures indicates thebottom member to which are attached side members 76 and 77 and the endmembers 78 and 79. Connected to the side member 77 are the corner pieces8O and 81 and connected to theside member 76 is the corner piece 82 andthe corner piece 83. It will be seen that the corner pieces 80, 81 and82 conform to the width of the side and end members, while the cornerpiece 83 is extended and has attached thereto the additional pieces 84and 85, the piece 83 being on two sides of thebox .instead of thelocking devices or'fasteningmeans 'of one .sec-v4 pieces 8O and 82 willlap the end members 78. Thepiece. 85. is provided with a hook 86 and thecornery ypiece '82y is' slotted at875, the hook 86 beingintended toengage with the slot 87 when the sectionhas been formed as abovedescribed.y

The partsi, 83, 84, 85 and -82 will be heldv in cell iormkby theengagement of the .hook

86 with .the slot 87 and the other wall members of the blankwillbe-placed inside of the cell of the section thatis intended to beused onfthe outside of the box land will be placed on the outside of thecell of the sectionthat is to be used on the inside of the box.

In Fig.l 20 .I have shown one of these. Ablanks folded to form the-outersection ofi the. box and in Fig. 21 I haveshown one of these," blanksfoldedtovform the inner section off the box. Byputtingthe section shownin. Fig. 21 inside of the 'section-showniniFig. .I

20, the loose parts of each will be heldbythe other or between the twosections..

It will be lunderstood --that lin using-the blanks shown .in'Figsz'l and17 the corner pieces may be fastened together by vany means other thanwhat are Ishown -or-.by the use of an adhesive'and the side and-:end

members will be bent up v'from the blank to form the section therefrom.

In case'the box made from 'blanksy similar to those shown in Figs. 16and 17 is to be of such a height that the corner pieces nor mally willbe less thanfthe. desired length,

the vside or vend members or both-may -be widened out and the cornerpieces maybe `extended to correspond `in the making of the blank. Insuch'vea'se theside -orl end` members or both'will have .excess width otstock similar to `some of the members .1n the blanks `shown in Figs. 1to'l. In the fin-r lishedsection the excess width ofthese members .willbe folded over the =corner'pi eces..to form lockingl strips as isdescribedin connectionfwith Figs. .l to 15.

In all'casesv the corner. pieces .may also fastened together by anysuitable lmeans in addition tothe locking strips providedtheyv` are ofsufficient length to lap each other.

If desired two or more blanks of the same kind as forexample .such asare shown v1n Fig. 1 may l.be usedfin the makingof a boX... When similarblanks of the lkind shownin Figs. 1 to 17 inclusive are yused inthevsame box, the locking devices or fastening. means of all blanks orsections will vcome together tionbeing located on. sides that are inten.mediate .the .sides on which the locking de.-

It will be also understood that boxes of this sort may be made of anysize, dimension or shape.

It will also be understood that in the blanks herein described therewill be little or no waste material andl that the internal strippingoperation or the removal of waste material from the inner part of theblank is eliminated, the stripping being confined where necessary,entirely .to the outer edges of the blank and consequently the blankscan be readily formed from roll stock.

It is evident that the box as made from the blanks as shown in Figs. lto15 and by f the method as described above is particularly adapted tobe manufactured by automatic machinery, since there is no internalstripping to form'finished blanks and no hooking of members involved inthe folding comprising membersto form endy and side walls and a bottom,each of said Asections having complete locking means adaptedto hold partof its members in box form, said sections being Aassembled one. within.another so the bottom members superimpose and the loose members of eachsection are held in place between the locked members of their ownsection and the members of the next adjacent section.

4. An open box comprising a plurality of separate box sections, each ofsaid sections comprising members to form end andside walls and a bottom,each of said sections having complete locking means adapted to hold partof its members in box form, said sections being assembled one withinanother so the bottom members superimpose and the loose members of eachsection are held in place between the locked members of their' and theloose members of each section are held in place between the lockedmembers of their own section and the members of the next adjacentsection, and corner portions of one or more bottom members adapted to beturned up and held between the sections to seal and strengthen thelowercorners of the box.

6. An open box comprising a plurality of separate box sections, eachofsaid sections comprising members to form end and side walls and abottom, each of said sections having complete locking means adapted tohold part of its members in box form, said sections being assembled onewithin another so the locking means of one section are at right ang-lesto the locking means of the next adjacent section with the bottommembers superimposed, the loose members of each section being held inplace between the locked members of their own section and the members ofthe next adjacent section.
